佩森船用脫硫塔系統(tǒng)為模塊化設(shè)計，包含脫硫塔，噴淋系統(tǒng)，堿液系統(tǒng)，水處理系統(tǒng)，連續(xù)監(jiān)測系統(tǒng)和控制系統(tǒng)，根據(jù)每艘船的不同要求要求量身定制，可同時用于U型和I型模型，可用于開式、閉式和混合式三種不同模式。

 POT DeSOx scrubber is designed by her own in-house R&D and technology and engineering team dedicated in scrubbers for ships,  which have obtained ABS, LR and  CCS certificate already.

POT DeSOx Scrubber consists of scrubber tower, spray system, NaOH system, water treatment system, Continuous monitoring systems and control system. Scrubbers will be tailored to suit each individual vessel, depending on her operational requirements. POT is capable for both the U-type and I-type models for Open Loop mode, Closed Loop mode and Hybrid modes, be single-stream or multi-stream.

開式系統(tǒng) / Open Loop Mode  ▼

在開式系統(tǒng)中，海水被用來作為洗滌水清洗廢氣。海水通常呈堿性，PH值為7.8~8.3，海水中含有能中和H+的物質(zhì)，如碳酸氫根、碳酸鹽等，是海水對廢氣中SOX洗滌的物質(zhì)基礎(chǔ)，另外海水中還含有大量的可溶鹽、硫酸鹽等，這些可溶解鹽，可與其酸式鹽進(jìn)行相互轉(zhuǎn)換，所以海洋是一個具有天然堿度的巨大的酸堿平衡緩沖體。利用海水具有的天然堿度和酸堿緩沖能力吸收煙氣中的SO2，并恢復(fù)脫硫后海水的PH值，既達(dá)到了煙氣脫硫的目的，又滿足了海水達(dá)標(biāo)排放要求。 

開式系統(tǒng)適用范圍

1. ECA控制排放區(qū)以外海域； 2. 其它區(qū)域的離岸200海里外，及公海海域 

Using the natural alkalinity and acid-base buffer capacity of seawater to absorb Sox in flue gas and restore the PH value of seawater after desulfurization, the purpose of flue gas desulfurization is achieved and the effluent discharged is monitored in compliance with IMO and VGP regulations.

閉式系統(tǒng) / Closed Loop Mode  ▼

閉式循環(huán)的洗滌液體介質(zhì)為海水或淡水，一般用于低堿性或淡水水域，通過在洗滌液體中添加高濃度堿液，完成對廢氣中SO2的洗滌，恢復(fù)脫硫后洗滌水的PH值，即達(dá)到了對廢氣中SOx洗滌的目的。本系統(tǒng)中的洗滌液體可循環(huán)使用，同時適用于排放要求比較高的海區(qū)，可滿足零排放要求。本系統(tǒng)運行功率較開式系統(tǒng)小。

閉式系統(tǒng)適用范圍 

1、ECA控制排放區(qū)以內(nèi)海域；

2、或全海域 ；

The washwater medium is seawater or fresh water.

When this mode is applied, washed water is treated and recirculated, and NaOH of high concentration is  added to increase its buffering capacity and DeSOx neutralization. After this process, the wash water is recycled.

This mode is capable of meeting zero discharge requirement.

混合系統(tǒng) / Hybrid Mode  ▼

混合系統(tǒng)同時包含開式和閉式系統(tǒng)，在混合系統(tǒng)中可以對兩種模式進(jìn)行相互切換，兩種系統(tǒng)模式的應(yīng)用取決于海水堿度、排放限制等條件。在開放海域航行時， 該系統(tǒng)通常在開環(huán)模式下運行以減少鈉堿和洗滌水的消耗。當(dāng)靠港或進(jìn)入排放控制區(qū)時，該系統(tǒng)通常在閉環(huán)模式下運行。

This mode allows vessel to operate in both open loop mode and closed loop mode. Hybrid mode offers the flexibility to switch between open loop mode and closed loop mode in different sea areas, and meets operational requirements, so as to achieve complementary purposes, and cost savings when applied to all sea areas.
